The Rundown: TikTok just launched Symphony, a new suite of AI features to help brands and creators produce content more efficiently on the platform — including digital avatars, translation tools, an AI assistant, and more.

The details:

  • Symphony Digital Avatars enable brands to generate AI spokespeople to star in their TikTok ads and branded content across multiple languages.

  • Brands can choose from a selection of ‘stock avatars’ based on real actors or create custom avatars to serve as virtual brand reps.

  • A new AI Dubbing tool automatically transcribes, translates, and dubs videos into 10+ languages, helping brands scale content globally.

  • TikTok’s Creative Assistant has been rebranded to Symphony Assistant, a chatbot to help with brainstorming, writing scripts, and optimizing content for the platform.

Why it matters: The creator economy is about to be completely remade with AI, and these tools will unlock new opportunities for optimized content, reach, and creation — but the rise of digital ‘spokespeople’ will also raise new questions on authenticity and consumer trust that brands will need to grapple with.

The Rundown: Meta's Fundamental AI Research (FAIR) group just published an array of new open-source AI models and techniques, including releases for multimodal language tasks, text-to-music and audio, detecting synthetic speech, and more.

The details:

  • Chameleon is a family of language models (7B and 34B parameters) that can handle image, audio, and text inputs together — previously introduced in May.

  • JASCO is Meta's new controllable text-to-music model, allowing for granular input controls to guide music generation.

  • AudioSeal is the first audio watermarking model specifically for detecting AI-generated speech, released under a commercial license.

  • Meta's Multi-Token Prediction model aims to improve code autocompletion by predicting multiple tokens at a time, improving speed and capabilities.

Why it matters: Meta just released a wealth of new open-source goodies, continuing to advance research across the AI landscape. AudioSeal’s AI-audio detection will be particularly interesting to watch, given the industry’s struggle to reliably ID other content like text and images.

The Rundown: Researchers at the University of Cincinnati just developed a new AI system that can predict anxiety levels using a short picture rating task and a small set of demography and psychological variables.

The details:

  • Comp Cog AI combines principles from psychology with machine learning to measure human decision-making patterns related to anxiety.

  • Participants rate a series of emotion-evoking pictures and answer a few contextual questions about their age, income, employment, etc.

  • The model extracts 15 ‘judgment variables’ that capture patterns in how users weigh positive and negative outcomes in decision-making.

  • In tests, the model predicted whether participants had higher or lower anxiety with up to 81% accuracy.

Why it matters: While anxiety disorders are extremely prevalent, they’re also often challenging and time-consuming to diagnose. With AI’s ability to connect data patterns and achieve reliable predictions, the tech could soon enable more efficient screenings to streamline assessment and treatment time.
